Recharge Your Mind With Sleep

The key to mental clarity might just be about getting a better sleep

The human mind is abuzz with thoughts all day, from experiencing a wide spectrum of emotions and the multitasking required in both work and family to the distraction from media and electronic devices.

“Our mind produces electrical and chemical activity in the brain,” says Catherine Roscoe Barr, BSc. in neuroscience, wellness coach and founder of The Life Delicious (thelifedelicious.ca).

“All cellular activity produces waste material, and the latest science reveals sleep’s role in ‘cleaning’ waste material from our brain. This housekeeping function is primarily active while we sleep and has significant implications for mood regulation, cognitive function, and neurodegenerative diseases.

To recharge our mind and keep brain and body healthy, we must practice good sleep hygiene.

“Reducing both stress—mental, physical and nutritional—and light pollution can help you sleep better,” says Roscoe Barr, and all it takes are a few simple tweaks to your daily routine and home environment.

“Limiting stressful conversations, intense physical activity, and stimulating foods like caffeine, alcohol and sugar in the hours before bedtime will help reduce cortisol,” says Roscoe Barr, “while reducing light pollution—especially blue light emitted from fluorescent and LED lights and the screens of your mobile phone, computer and TV—will facilitate melatonin production to help you fall, and stay, asleep.”

Tips for better sleep hygiene

To recharge your mind and allow your brain to do its nightly custodial work, practice this series of rituals as the sun sets:
